1,264,603,l spemuon o: man ramt. Patented Apr, 30, 1913, Applicationtiled Inrch 24, 1917. Serial No. 157,212. To all rwhom tmay concern:vided in itsl upperl wall with an opening Be it known that I, HUGH A.BLACK2 a subject of the King of Great Britain, resld-` ing at Vancouver,in the Province `pf British Columbia and Dominion of Canada, haveinventedcertain new and useful vImprovements in Dispensing-Machines, ofwhich the 'following is a specliication.

This invention relates to an improved coin controlled vending machine ofthe rotary drum type and the principal lobject ofthe invention is'to proe improved means for rotating the drum in order to brin a compartmentthereofinto operative re ation to the outlet spout of the machine,.tofurther provide improved means for moving the closures of the drum,compartment to an open position, to so construct'the machine that thedrum turninglever cannot be moved unless a coin is placed in the coinchute and to further so construct the machine that a signal bell will berung when the drum has made a com lete revolution. v

Another o ject of the invention is to so construct and mount the closureopening `device that it may be moved and releasably held in an inoerative position when filling the machine ms preventing the closuresfrom opening while filling the machine.

This invention is illustrated in the accompanying drawings, whereinFigure 1 is a. view shown with the housing in vertical section the viewbeing taken along the line 1-1 of Fig. 3. I

Fig. 2 is a vertical sectional view taken along the line 2-#2 of Fig. 3.

Fig. 3-is a vertical transverse sectional view taken alon the line 3-3of Fig. 1.

Fig. 4 is a agmentary sectional view through the drum and housing takenalong the line 4 4 of Fig. 1. i -1 i Fig. 5 is a fragmentary sectionalview taken along the line 5'5 of Fig. 1. i

Fig. 6 is a fragmentary sectional view through the coin chute takenalong the line 6 6 of Fig. 1.

Fig. 7 is a fragmentarysectional view`V through the drum.

This improved coin controlled vending machine is provided with a housing10 hav ing an'outlet 11 through which extends the chute 12 for themerchandise to be sold. This housing is further provided with a closure13 for permitting access to the interior of the housing for rellin andremoving the coin in the coin tray or x 14 and is prothrough whichextends the upper end portion of the coin chute 15. This coin chutehousing so that the plunger may be moved downwardly after a coin hasbeen .placed in the coin chute. A spring 22 is connected with thehousing and with the ,upper end portion of the plunger thus serving toyieldabrl7 hold-the plunger in a raised position. he drum 23 is mountedupon a shaft 24 journaled in the side walls of the housing 10, the shaftcarrying a ratchet wheel 25 for engagement by the pawl 26 carried by thearms 27 of the actuating lever 28. This actuating lever extends beneath.the abutment or bumper 29 and is engaged by the spring 30 wh1chnormally holds the actuating lever in-'the position shown in Fig; 1

lwith its free end portion extending' into the coin chute at the upperend of the chamber 17. When a coin is placed in the chute 15, it passesdown into the chute at thebase of the neck 19 where it will rest uponthe free end portion of the actuating'lever 28. The

plunger 18 can then be moved downwardly and'will engage the coin andthrough the mediumof the coin will swin positioned in the chamber 17will slip past the ylever and the spring 30 will return the lever to theposition shown in Fig. 1 as soon as the plunger has returned'to itsnormal position. In order to prevent the drum from moving beyond adesired amount there has been provided a latch 31 of the spring -pressedtype fitting into a socket 32 and enaged by a spring 33 thereinso thatthis ntch pin will be held extended for fitting into the recesses 34formedin the side wall of the drum. I

The drum is provided with a plurality o f compartments 35 having trays36 positioned therein and provided with closure doors 37 hingedlymounted as shown at 38 and yieldably held in a closed position bysprings 39.

`These closure doors 37 are provided with pins 40 which eXtend beyondthe side of the drum for engagement with the cam 41 as indicated in Fig.2 by dotted lines. As these arms or pins 40 engage the cam, they willmove the closures to an open position thus permitting the contents ofthe compartments 35 to drop upon the chute 12.l This cam 41 is pivotallymounted and is provided with a bracing bar 42V which will normally be inengagement with pin 43 thus holding the cam extended as shown in Figs. 1and 2. When it is desired to ill the machine, it will of course Anot bedesired to have the compartments empty upon reaching the opl relation tothe strikers 46 which strikers engage the ratchet wheel 47. A pin 48extends from the drum and after the drum makes a complete revolution,this pin will engage the pawl or lever 49 and move the pawl so that theratchet wheel will rotate thus moving the strikers 46 to ring the signalbell 45. Therefore this signal would serve both to indicate that themachine has been completely emptied and further as means for indicatinthat the filling was completed.

t will thus be seen that there has been provided a dispensing machine inwhich the coins may be placed in the coin chute and the plunger 18 thenmoved downwardly to bring the coin into engagement with the lever 28 andmove the lever to rotate the drum thus bringing a filled compartmentinto operative relation to the chute 12 with the closure door of thecompartment opening to permit the contents of the compartment to dropupon the chute. It will be further noted that this machine cannot beoperated unless the coin is placedv in the chute for without the coinbeing in place, the lunger 18 cannot reach the lever 28. It w1ll befurther noted that the drum will be prevented from moving beyond adesired amount for one operation due to the fact that the ring latch pin31 will prevent rotation of t e drum beyond a desired amount.

It will be' further noted that the machine can be easily refilled andthe coins removed from the coin tray when the closure door 13 is removedand further that when filling, the closures 37 can be prevented fromopening by moving the cam 41 to an inoperative position. It will thus beseen that there has been provided a very eiicient coin controlleddispensing machine which may be built in any size and for any size ofcoin according to the value and quantity of goods to be dispensed.

What is claimed is 1. A vending machine comprising a housing, a drumrotatably mounted in the housing and provided with article receivingchambers, closures for the chambers movably mounted and yieldably heldin a closed position, abutments extending from the closures, a cammounted for engagement with the abutments to engage the abutments andmove the closures to an open position as the drum rotates, and means forrotating the drum.

2. A vending machine comprising a vhousing, a drum rotatably mounted insaid housing and provided with article receiving compartments, closuresfor the compartments movably mounted and yieldably held in a closedposition, a cam movably mounted in the housing, abutments extending fromthe closures for engagingthe cam and moving the closures to an openosition as the drum Vis moved to successive y bring the articlecompartments into operative relation to the outlet of the housing, abracing vrod connected with the cam element for holding the cam elementin an adjusted position for engagement with the abutments .0f theclosures when in one position and for permitting the .drum to rotatewithout the abutments enthe cam element when the cam elegagin g andmeans for mentI 1s in a set position, rotating the drum.

In testimony whereof I affix my signature in presence of two witnesses.
